Application filed a riiia, 1912.

To all whom it may concern;

Be it known that I, JAMES E.

United States, residing provide a silo which is formed of a plural 1ty of sections having interlocking connections whereby a silo can be easily and quickly installed or taken down, in order to allow the same to be transported from place to place.

Another object'of the invention is to provide a silo in which the sections are united in such a manner that a substantially air tight joint is formed locked. 2

Another object of the invention is to provide a silo in which the sections are arranged staggered whereby the silo will be strengthened in order to prevent the same from yielding the lap-joint of one pair of sections coming under the center portions of the adjacent sections. v

With these objects in view: Figure 1, is a side elevation of three'sections interlocked together showing the staggered arrangement thereof; Fig. 2, is a longitudinal horizontal section through a pair of sections; Fig. 3, is a section taken on the line 6 6 of. Fig. 1; Fig. l, is a detail front elevation of one of the sections; and Fig. 5, is, a perspective view of one'of the sections.

In constructing a silo according to my in vention, I employ a plurality of longitudinally curved sections 5 provided with interlocking means 'at their marginal edges as uch shape that when a clearly shown, said sections being staggeredly arranged as shown in Fig. l.

The sections are preferably formed rectangular in shape, and are bent outwardly and heel: upon themselves to form substantially .U-shaped portions 6 and 7 on their horizontal edges, said 'U-shaped portions terv minating in vertical flanges 8 and 9. The ends of the sections are also bent outwardly and back upon themselves to form substan tially 'U-shaped portions .10 and 11 termimating in fiange portions 12 and 13. The U-shaped portions 11 and 'Z are bent into series of these Specification of Letters Patent.

sections are united they will fit within the U-shaped portions 6 and 10 and, as shown in Fig. 1, the sections are united and secured by bolts passing through the 60,

flange portion of Y tions and as clearly shown in Fig. 1, when a series of these sections are united, a sub-v ,stantially air-tight joint is formed between the sections. ,It will also be seen that each secti'on,when bent into its proper shape, is

substantially box-shape, that is, a marginal lateral flangenis formed upon its four edges. which terminates in a flan e extending in the same plane as the hod y of the plate. When the sections are united'the interlocking vertical portions of the abutting sections of the interlocking are arranged centrally section arranged above and below, and as shown, the flanges lop over in order to form a water-tight joint.

i While I have shown and described the inso terlockingconnections at the marginaledges of each'section, constructed in this particular: manner, it of course being understood that the joints canhe formed reverse to that shown and that any can be used without spirit of my invention.

From the foregoing description it will be seen that I have provided a silo which is formed of a plurality curved sections which are united to form a complete circle at their abutting ends and these sections are preferably formed of a suitable sheet metal which will yield in order to allow the same the proper curvature. It will also be seen that thesections are interlocked at their up per and lower edges in such a manner that it is impossible for sections to accidentally become detached I I In the perspective view of the section shown in Fig. 5, the section is straight instead of curved longitudinally and in ome cases a section of this construction will ave advantages over a curved section, -the same is sprung to for'ma curve, the interlockingends of the adjacent sections will be held firmly together.

What I claim is: 1. A circular silo. formed. staggeredly arranged sections, each section composed of a longitudinally curved metal departing from the of longitudinally to be bent to assume as when of a plurality of.

reck-angular plate bent to form horizontal U- shopeo. pork-ions upon its upper onci lower edges terminating in vertical flanges and upon its ends in vertical U-shopeci portions Eerminating in flanges, the verticai flange o the iower horizonisi portion being centmiiy notcheci, one of each of the vertical and horizontal U-shripezi portions being capable of fitting Wig/hill ii-shaped. portions of "be adjacent seetion, the veriicai i-shaped. iorcions fitting in ine 'ootci'ies' oi the adjoe-ent section orderio support the =Li-shoped portion midway between its iengh.

2. A cylindrical silo form'eei of o. piuroiity of iongituinoily curve-2i reecangn. sections inning so siomisii horizonioiiy, orally projecting 'iB-siuipefl. portions oiijooen'b the upper and; iower e iges faiieiieo'f terzi'iinating in flanges arranged his .e the body I sire sedition, one veriicoiiy laterin presence of two oily projeoiing subsiantiaiiy Ushoperi per tions adjooent their ends terminating in flanges arranged. in the piano of the bottom of the sections, the lower flange oi each section being centrally notched, she ifi shapee'i portions 01. said sections being interiocizeii together the interlocking ends of one pair of sections fitting in the central notches the section. above, onoi the interlocking Verti cal and horizontoi portions of seici sections being in vereicoi and horizontal oli'nement respectively when arranged to form a compiete silo,

In eestimony whereof I affix my signature witnesses.
